Definitions

  • the invention relates to treating heart disease, and more particularly systems, devices and methods for reestablishing or improving blood flow to the myocardium.
  • Coronary artery disease is currently treated by interventional procedures such as percutaneous transluminal coronary angioplasty (PTC A), atherectomy and intracoronary stenting, as well as surgical procedures including coronary artery bypass grafting (CABG).
  • PTC A percutaneous transluminal coronary angioplasty
  • CABG coronary artery bypass grafting
  • the goal of these procedures is to reestablish or improve blood flow through occluded (or partially occluded) coronary arteries, which is accomplished, for example, by enlarging the blood flow lumen of the artery or by forming a bypass that allows blood to circumvent the occlusion.
  • What procedure(s) is used typically depends on the severity and location of the blockages. When successful, these procedures restore blood flow to myocardial tissue that had not been sufficiently perfused due to the occlusion.
  • the invention provides a device and method for engaging tissue of a coronary vessel or heart wall during a cardiovascular procedure.
  • a device constructed according to this embodiment includes first and second members coupled together so as to permit relative movement.
  • a tissue engaging mechanism is coupled to the first and second members and moves between first and second positions. In the preferred embodiment, the first and second positions are collapsed and expanded orientations.
  • the tissue engaging mechanism includes at least one tissue engaging member that contacts engage body tissue when in the expanded orientation.
  • a method carried out according to this embodiment includes steps of providing a tissue support device having a tissue engaging mechanism configured to assume an expanded, tissue supporting orientation, positioning the tissue support device through the wall of a patient's heart and locating the tissue engaging mechanism adjacent tissue, and placing the tissue engaging mechanism in the expanded, tissue supporting orientation in engagement with the tissue.
  • the invention provides a device and method for supporting a wall of a vascular structure in order to access the lumen of the vascular structure.
  • a device constructed according to this embodiment includes a support structure adapted to be positioned in the lumen of a vascular structure, the support structure comprising a plurality of support elements coupled together so as to be movable relative to each other. The support elements move relative to each other to move the support structure from a collapsed orientation to an expanded orientation in order to support a wall of a vascular structure, and are sized and configured so that when the support structure is in the expanded orientation the support elements engage the wall of the vascular structure to prevent the wall from collapsing.
  • Another device constructed according to this embodiment includes an introducer having a hollow interior and an elongated support member configured to be generally coiled when in an unbiased orientation and generally straight when in a biased orientation.
  • the interior of the introducer is sized and configured to receive the elongated support member and hold the support member in the generally straight, biased orientation.
  • the elongated support member is moved from the straight, biased orientation within the interior of the introducer to the coiled, unbiased orientation upon entering the interior of the vascular structure to support the vascular structure.
  • a method carried out according to this embodiment includes steps of positioning a support within an interior of a vascular structure such that the support contacts and supports a wall of the vascular structure, and introducing a medical device into the interior of the vascular structure by passing the device through the wall of the vascular structure and through the support.
  • the invention provides a device and method for stabilizing an area of a patient's heart adjacent a coronary vessel.
  • a device constructed according to this embodiment includes a base configured to be positioned adjacent a coronary vessel of a patient's heart, the base having at least one opening for accessing the coronary vessel.
  • At least one tissue engaging element is coupled to the base so as to be movable with respect to the base, the tissue engaging element having a portion configured to securely engage the wall of a patient's heart in order to stabilize the wall of the heart upon moving the tissue engaging element with respect to the base.
  • An actuator is provided for imparting relative movement to the base and the tissue engaging element in order to stabilize the heart while accessing the coronary vessel through the opening in the base.
  • the invention provides a conduit for placing a coronary vessel of a patient's heart in communication with a heart chamber.
  • the conduit is in the form of a tubular element including first and second portions having different cross-sectional sizes and a bore defining a blood flow path.
  • the cross-section of the first portion of the tubular element is larger than the cross-section of the second portion such that the tubular element is generally funnel-shaped, and the first and second portions of the tubular element are generally aligned so that the bore defines a generally straight blood flow path.
  • the invention provides a conduit for communicating a chamber of a patient's heart with a coronary vessel.
  • the conduit is in the form of an expandable stent including first and second portions having different cross- sectional sizes when the stent is expanded.
  • Each of the first and second portions of the stent includes strut members disposed along a first direction when the stent is unexpended and along a second direction when the stent is expanded, the second direction being transverse to the first direction.
  • the strut members of the first portion are longer than the strut members of the second portion so that the stent is generally funnel-shaped when expanded.
  • the invention provides a conduit is in the form of an expandable tubular element having first and second portions with different cross- sectional sizes.
  • This tubular element is preferably a coronary stent constructed so that the first and second portions are disposed in an orientation that provides the stent with maximum radial strength when expanded.
  • the invention provides a conduit for placing a coronary vessel in communication with a heart chamber, the conduit including a vessel support mechanism configured to contact and support the vessel wall when the conduit is positioned in the heart wall.
